“…The formation of different oxygen containing functional groups in a APPJ in air as well as the modification of the surface roughness of the polymer surfaces depending on the gas nature and plasma power were correlated to the improvement of adhesion to different materials. Such properties depended on the operating conditions of the plasma used in particularly the plasma gas, the plasma power or frequency …”

http://www.interscience.wiley.com/International audienceSurface activation of polymers by atmospheric pressure plasma is an economically important process for bonding technologies. Although most of the studies are focused on the modification of the surface chemistry, this study investigates the modification of the topmost surface and the deeper layers of a polyamide-6 sheet treated by an open-air atmospheric plasma jet system. The plasma jet used in this study is a unique combination of highly reactive species (e.g. O8, 8OH. . .) and a high temperature gas estimated (from 600–1 000 K) which leads to surface functionalization,amorphization and polymorphism modification. The results have shown that an amorphization of the polyamide occurs on the top surface. Moreover, a crystallization of the amorphous phase in the a form was also highlighted in the depth of the material

“…The surface compositions of the untreated and treated ePTFE samples were examined by XPS. In terms of binding energy, the peaks at 285, 532, and 685 eV corresponded to the C 1s, O 1s, and F 1s, respectively . The XPS survey spectrum of the original ePTFE film showed the peaks of carbon and fluorine as seen in Fig.…”

A two-step process based on a low-pressure helium plasma treatment followed by acrylic acid-grafting copolymerization was used for the surface modification of expanded polytetrafluoroethylene (ePTFE) films. The effects of plasma treatment power and treatment time on the hydrophilicity of the film surface were investigated. The wettability of the ePTFE film surface was characterized by water contact angle, and the surface compositions of the untreated and treated ePTFE samples were evaluated by atomic force microscopy and XPS. Contact angle measurements revealed that the hydrophilicity of the ePTFE film surface was greatly enhanced by the combined actions of the plasma treatment and acrylic acid grafting, and the contact angle decreased from 145 to 66 . Atomic force microscopy analyses showed that the surface roughness increased after the plasma treatment. XPS analyses showed substantial increase in the concentration of carbon and oxygen atoms and a decrease in the concentration of fluorine atoms at the film surface. T-peel strength showed an improved bonding strength between the film and an adhesive tape after the treatment.
